One of my trader friend lost all margin money in his account doing trading (may be 3-4 time in his trading carrier). He told me that he arranged once again margin money to start trading.
My advice to him that the trading money and margin money is two different thing. Margin money will help to take a position, but trading money required for win a trade.
Trading money is equal to Stop Loss required as per your system.
Trading money should be 3-4 time of your Stop Loss, because some time 2 continue SL trigger and third one may be winning trade.
The winning trade always more than Stop Loss, so you may continue as successful trader.
